Abstract

An influence of a time step value on stability and convergence is analyzed for solutions of numerical simulation problems associated with plasma flow around a body. It has been established that the Courant- Friedrichs-Levy condition for the time step is too strict as applies to the problem mentioned above. A possibility is proved to multiply up many times the time step value providing considerable saving of computer resources
